the O
2
sensor is removed.
1. Select the icon > [O
2
] soft key.
2. Remove the O

sensor port on the breathing system. Allow three (3) minutes
for the sensor to acclimate to the environment.
3. Carefully follow the on-screen prompts to prepare for calibration.
4. Select the [Begin] key to start the O
2
sensor calibration. The system will display the calibration
status after calibration has completed.
5. If an error code (such as 00 00 00 10) is displayed in red, see "O2 sensor calibration error codes",
Table 9-2 on Pages 9-6 to learn more about troubleshooting. When the 21% O
2
calibration is
complete, reinstall the O
2
sensor to the O
2
sensor port on the breathing system.
9.4.2 100% O
2
Calibration
When the measured O
2
concentration evidently diverges from other reference values, or when the
O
2
sensor is replaced, the sensor should be calibrated. When the O
2
sensor is replaced, 100% O
2
calibration is required.
1. Make sure that the anesthesia system is in the standby mode.
2. Select the icon > [System] (system password required) > [Calibrate] > [O
2
Sensor] soft
key.
3. Make sure that no [O
2
Supply Failure] alarm appears.
4. Carefully follow the on-screen prompts to prepare for calibration.
5. Select the [Begin] key to start the 100% O
2
sensor calibration. The system will prompt the
calibration status after calibration has completed.
6. If error code (such as 00 00 00 10) is displayed in red, see "O2 sensor calibration error codes",
Table 9-2 on Pages 9-6 to learn more about troubleshooting.
7. After the calibration is complete, select to close the menu.
NOTE: If the 100% O
2
calibration failed, check for any technical faults and
alarms. After the fault is cleared, calibrate the sensor again.
NOTE: If the calibration failed for several times, replace the O
2
sensor and
calibrate the sensor again. If the calibration failure persists, contact
Mindray Technical Support.
